Anthurium plant named ‘ANTHDUDKA’

ABSTRACT

A new and distinct  Anthurium  plant named ‘ANTHDUDKA’ particularly distinguished by having shiny, bright red, cordate and very durable spathes that retain the original color for a very long period of time, dark green and long cordate, durable leaves, white spadix with yellow tip, early and rich flowering continuously throughout the year and a plant height of 26.0 cm to 28.0 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDUDKA’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHDUDKA’. This new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, The Netherlands. The objective of this breeding program was to create a new plant with bright red spathes and a compact plant habit intended for small pot sizes (diameter 9 to 12 cm).

The new variety originated from a cross-pollination made in November 2006 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘ANTHOLODOJ’ (U.S. Plant Pat. No. 20,254), and the male parent was an orange Anthurium plant designated ‘10520-03’ (unpatented).

A single plant was selected in November 2008 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a seven-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 6, 2014. ‘ANTHDUDKA’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Shiny, bright red, cordate spathe;     -   2) White spadix with yellow tip;     -   3) Green cordate leaves;     -   4) The base of the older flowers becomes brown-red; and     -   5) Hardly no pollen production.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 35-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in January 2016. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 3 shows the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDUDKA’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 35-week old plants which were planted from tissue culture in 12-centimeter diameter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in January 2016. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

When the spadix matures, small stigmata protrude. The             stigmata are evenly distributed round the spadix. The spadix             matures from base to top, slowly giving the spadix a             somewhat rough appearance.         -   Color.—Immature: RHS 13C. Mature: RHS 155B.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDUDKA’ differs from the female parent plant ‘ANTHOLODOJ’ (U.S. Plant Pat. No. 20,254) in that ‘ANTHDUDKA’ has ovate cordate shaped leaves and spathes, whereas ‘ANTHOLODOJ’ has elliptical cordate shaped leaves and spathes. Additionally, the spadix length of ‘ANTHDUDKA’ is shorter than the spadix length of ‘ANTHOLODOJ’.

‘ANTHDUDKA’ differs from male parent plant ‘10520-03’ (unpatented) in that the spathes of ‘ANTHDUDKA’ are red, whereas the spathes of ‘10520-03’ are orange. Additionally, ‘ANTHDUDKA’ has ovate cordate shaped leaves, while ‘10520-03’ has elliptical cordate shaped leaves.

‘ANTHDUDKA’ differs from commercial variety ‘ANTHCOZAM’ (unpatented) in that ‘ANTHDUDKA’ has yellow immature spadix, white flowers and red spathes, whereas ‘ANTHCOZAM’ has orange immature spadix, orange-red flowers and dark red spathes. Additionally, ‘ANTHDUDKA’ has ovate cordate shaped leaves and flat spathes, whereas ‘ANTHCOZAM’ has elliptical cordate shaped leaves and wavy spathes.

‘ANTHDUDKA’ differs from commercial variety ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in that ‘ANTHDUDKA’ has immature spadix that are yellow and spathes that are flat, whereas ‘ANTHEPEDI’ has immature spadix that are yellow-orange and spathes that are cupped. Additionally, the cataphyll of ‘ANTHDUDKA’ are grey-red, whereas the cataphyll of ‘ANTHEPEDI’ are light green. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHDUDKA’, substantially as illustrated and described herein.
